Abstract: 963,143. Electric wiring arrangements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Oct. 13, 1960 [Oct. 13, 1959], No. 34650/59. Heading H1R. Data processing apparatus includes an assemblage of basic logical units which are interconnected to perform logical functions on data representing electrical signals, each logical unit having two or more input circuits and at least one output circuit, and the interconnections between the units necessary to effect the required logical operations being provided by two-wire open transmission lines having an impedance equal to that of the input circuits. Basic logical units 10, 11, 12 each consist of a circuit board 13 carrying a pulse amplifier 14, a multiinput AND gate 15 and a number of multiinput OR gates 16; the boards 13 being provided with a sufficient number of connection points to allow any of these basic circuits to be used separately. Output signals generated in the secondary windings of output transformer 17 by the pulse amplifier may be fed back to the input of an AND gate of the same unit to cause the latter to operate as a dynamic trigger circuit and are also fed to the input circuits of different basic units by means of two wire open transmission lines 18, 19. The transmission line may consist simply of two wires which are held at the required distance apart by insulating spacers which are provided with holes or grooves to accommodate the wires, or alternatively the line may be formed by embedding the wires in a synthetic plastic material in such a way that the wire spacing is determined by a thin web of the plastic material which joins the two wires together. The input circuits are designed to present an input impedance equal to the impedance of the transmission line. If a fault occurs in any of the units, then any of these units may be removed and replaced by a master board which carries components for all of the basic circuits in any of the units and which can be converted into any of the units by a small amount of cross wiring of the connection points.

Title: Improvements in means for periodically introducing pulverulent fuels into internal combustion engines
IPC: F02B45/02
Filed: 1929-11-13
Abstract: 340,709. Generating combustion products under pressure. HOLZWARTH, H., 7, Goethestrasse,Diisseldorf, Germany. Nov. 3, 1929, No. 34662. [Class 51 (i).] In an internalcombustion engine such as an explosion turbine using pulverulent fuel, the valve controlling the periodic supply of fuel is of the lift type. The valve head 23 is mounted by ribs 30 on a movable sleeve 31 and is arranged to seat on the open mouth of a tube 19 through which the coal dust is supplied. The conical head of the valve is fitted with a rubber bearing disc 25, and also with a resilient member 29 which holds up the coal dust while a charge is being measured, but allows it to be blown into the sleeve 33 when pressure air is admitted. The valve is reciprocated by cams 38, 39 acting through levers 40, 41. The air for blowing out the charge is admitted by a valve 56 to a space 62 and enters the charge space 45 by a narrow annulus 63. When the charge has been delivered, the pressure in the space 45 is relieved by actuating another valve which opens this space to atmosphere. These valves are controlled by oil under pressure supplied by a master distributer 85 shown in Fig. 6. The amount of coal dust in a charge is regulated by varying the size of the space 45. This is effected by moving axially the head 44. This head is carried by a screwed sleeve 34 which is engaged by a screwed member 37 mounted on the central sleeve 31. The member 37 may be rotated by hand or governor through gearing 51, 52, 53 from a shaft 54. Fig. 6 shows the general lay-out. A number of combustion chambers 1 .. 4 are arranged to supply a turbine. Coal dust is fed from a hopper 13 past the supply pipes 19 .. 22, controlled bv valves as shown in Fig. 1, by a worm 15, excess of dust being returned by a pipe 79 and an air jet 81 to the hopper. An electric motor 18 drives the worm 15, the cam shaft 43, and the master distributer 85. This distributer controls the oil which actuates the admission and discharge valves of the combustion chambers as well as the air valves referred to above.

Title: Improvements in or relating to the manufacture of goods of sponge-like or cellular rubber or similar material
Filed: 1936-12-18
Abstract: 487,334. Sponge rubber. INTERNATIONAL LATEX PROCESSES, Ltd., MURPHY, E. A., ROUND, A. A., and NORCROSS, T. Dec. 18, 1936, No. 34779. [Classes 70 and 87 (ii)] A process for the production of spongy or cellular rubber sheets or articles from frothed aqueous dispersions consists in setting the froth on an upwardly open stratum or in an upwardly open mould, subjecting the set froth to pressure applied by a perforated surface and vulcanizing in the compressed condition. Preferably the perforations in the surface are uniformly distributed. Examples of suitable shapes and arrangements of perforations are shown in Figs. 1., 2, and 3. In Fig. 1 the perforations are quarter-inch squares with <5>/16 ins. between centres. In Fig. 2, the round perforations are <5>/16 ins. diameter and are # ins. between centres. In Fig. 3, alternate round ended slots are 1# ins. long and <3>/16 ins. wide and the separating strips are <1>/10 ins. wide. Apparatus for the continuous production of sponge rubber sheets by the method of the invention is shown in Fig. 4, and comprises an endless belt 3 on which the frothed latex or like dispersion is spread, an upper endless perforated belt 8, side walls in the form of endless rubber bands 4 of substantially the same thickness as the final rubber sponge sheet, gelling chamber 6 and vulcanizing chamber 10. The froth is spread on to the belt 3 by a knife 5 to the required thickness and is then set by passing through the gelling chamber 6. This causes the froth to swell somewhat and the top surface becomes convex. The set froth is then passed into the vulcanizing chamber and under the perforated belt 8 which compresses it to its original thickness. Vulcanization is carried out by the method described in Specification 487,350, wet steam or boiling water being sprayed into the chamber. Specifications 332,525, 332,526, [both in Class 70], 422,171, and 431,410 also are referred to.
